Introduction
In general, low-grade fever refers to mild fever. A mild fever lasting for 20 days may be caused by environmental factors, tracheitis, rheumatic fever, systemic lupus erythematosus, tuberculosis, or other reasons. Patients are advised to seek medical attention promptly and undergo relevant examinations to determine the underlying cause. In addition, conditions such as cirrhosis and leukemia may also lead to persistent low-grade fever. It is recommended that patients visit an outpatient clinic at a qualified hospital for timely consultation.
Generally, low-grade fever refers to mild fever. A persistent low-grade fever lasting 20 days may be caused by environmental factors, tracheitis, rheumatic fever, systemic lupus erythematosus, tuberculosis, or other conditions. Patients are advised to seek timely medical attention and undergo relevant examinations to determine the underlying cause. Specific analyses are as follows:
1. Environmental Factors
If a person remains in a cold environment for an extended period, it may lead to a low-grade fever persisting for 20 days. It is recommended to change the environment promptly and wear additional clothing to reduce cold exposure and alleviate symptoms.
2. Tracheitis
A low-grade fever lasting 20 days may be related to tracheitis. Symptoms may include fever, cough, and sputum production. Treatment may involve anti-infective medications such as amoxicillin capsules or azithromycin capsules, taken under medical guidance.
3. Rheumatic Fever
Rheumatic disease is a type of non-purulent inflammatory condition, with clinical manifestations including persistent low-grade fever, sore throat, fatigue, and others. Medications such as acetaminophen tablets or ibuprofen sustained-release capsules may be used as directed by a physician for treatment.
4. Systemic Lupus Erythematosus
Systemic lupus erythematosus (SLE), an autoimmune disorder, often presents with persistent low-grade fever. This fever typically resolves quickly after taking medication but may recur once the medication is discontinued. It is recommended to undergo systematic treatment under a doctor's supervision using drugs such as hydroxychloroquine sulfate tablets or thalidomide tablets.
5. Tuberculosis
Patients with tuberculosis commonly experience low-grade fever in the afternoon. If the condition is not fully controlled during treatment, low-grade fever may persist. Patients may take medications such as isoniazid tablets or rifampicin capsules as prescribed by their doctor.
In addition, prolonged low-grade fever may also be caused by other conditions such as liver cirrhosis or leukemia. Patients are advised to promptly visit an outpatient clinic at a qualified medical institution for consultation. Under professional medical guidance, the exact cause should be identified and appropriate treatment initiated to avoid delays in managing the illness.
